    摘要： Methods and apparatus' of determining radio link quality are disclosed. According to various implementations, information indicating the time-frequency blocks to be monitored by a UE to enable the UE to locate a control channel is determined. The UE receives configuration information regarding resources used by a channel state information reference signal. It also receives configuration information regarding an interference measurement resource, as well as a channel state information reference signal. The channel state information reference signal uses the channel state information reference signal resources. A synchronization condition is determined based on the time frequency blocks to be monitored by the UE, the received channel state information reference signal and the interference measurement resource. The determined synchronization condition is sent to a higher layer.

    摘要： An apparatus and method for communicating control information (e.g., CQI, rank, and/or ACK/NACK) over a data channel (e.g., PUSCH) in the absence of user data includes storing a reference block size for transmission of control information of a first type (e.g., CQI) in memory of a wireless communication device. The reference block size is based on a predetermined quantity of information bits for the first type of control information. Responsive to a scheduling message containing an allocation of data channel transmission resources, the wireless device determines a quantity of the allocated resources to be encoded with control information of a second type (e.g., rank or ACK/NACK). The wireless device may further determine a quantity of the allocated resources to be encoded with control information of the first type and multiplex the encoded control information of the first and second types into a subframe for transmission over the data channel.

    摘要： A wireless base unit (102) supporting carrier aggregation determines a truncation time period (159, 169) in order to create a reduced subframe component (154, 164) on an additional component carrier (120) such that the truncated subframe component (154, 164) does not interfere with the control region (171, 172) of a subframe (170, 180) transmitted on an overlapping component carrier (130) by an uncoordinated second base unit (105). The wireless base unit (102) transmits the truncated subframe component (154, 164) and also transmits truncation time period information within a control region (151, 161) of an anchor carrier (110). A remote terminal (104, 108) that supports carrier aggregation searches a control region (151, 161) of a subframe (150, 160) transmitted on the anchor carrier (110) for truncation information and uses the truncation information to determine a boundary of a data region in a subframe component (154, 164) received on the additional component carrier (120).

    摘要： A communication is provided that schedules both Distributed Virtual Resource Blocks (DVRB) and Localized Virtual Resource Blocks (LVRB) in a same frequency channel, thereby obtaining the benefits of frequency selective scheduling while minimizing the uplink feedback overhead. In one embodiment of the invention, the communication system assigns one or more downlink Physical Resource Blocks (PRBs) of multiple downlink Physical Resource Blocks (PRBs) to each user equipment (UE) given an LVRB to produce at least one reserved PRB and multiple non-reserved PRBs and assigns a part of each PRB of the multiple non-reserved PRBs to a UE given a DVRB. In another embodiment of the invention, the communication system assigns PRBs pre-reserved for localized transmission to UEs scheduled for LVRBs and assigns parts of multiple PRBs pre-reserved for distributed transmission to each UE given a DVRB.
